The Buick Regal is an upscale mid-sized automobile that was first introduced by Buick for the 1973 model year. North American production ended in 2004 and began again in 2011. For the 2011 model year, Buick re-introduced the Regal to the North American market, positioned as an upscale sports sedan. Production and sales in China have continued since 1999.
For certain model years between 1973 and 2004, the Regal shared bodies and powertrains with the similar Buick Century. The current model (2011present) is a badge-engineered version of the Opel Insignia, known as the Vauxhall Insignia in the UK.
In 1987, a lightweight WE4 (Turbo T) option was offered. Only 1,547 of this variant were produced. The differences between a WE4 and the Grand National were the interior trim package, wheels, exterior badging, aluminum bumper supports, and aluminum rear brake drums as opposed to the Grand National's cast iron, making the WE4 a lighter and faster car. The rear spoiler was only available as a dealer installed option. 1987 was the only year that the LC2 Turbo option was available on any Regal, making it possible to even see a Limited with a vinyl landau roof and a power bulge turbo hood. Turbo Regal Limiteds were one of the rarest models of Turbo Regals produced second only to the GNX at 1,035 Turbo Limiteds. Turbo Regal Limiteds could be ordered with many options with most having chrome external trim but for $35 could have been built with the full black-out trim option making them extremely rare. Limiteds were treated to a very luxurious interior with plush carpeting and optional bench pillow seats and a column shift. The 1987 model would be the end of the manufacture of the RWD "G-Body" Regal, but GM had to extend the build of the Grand National to meet customer demand into December.
For the final year, 1987, Buick introduced the Limited Production GNX "Grand National Experimental" at $29,900. Produced by McLaren Performance Technologies/ASC, Buick produced 547 Grand National with the interior trim Package. They were then sent off to McLaren Performance Technologies and upgraded into the Buick GNX. Buick underrated the GNX at 276 hp (206 kW) and a very substantial 360 lbft (488 Nm) of torque (actual output is 300 hp/224 kW and 420 lbft/569Nm). This was created to be the "Grand National to end all Grand Nationals." Changes made included a special Garrett T-3 turbocharger with a ceramic-impeller blowing through a more efficient and significantly larger capacity intercooler with a "CERMATEL (Ceramic/Aluminum) coated" pipe connecting the intercooler to the engine. A GNX specific E-EPROM, low-restriction exhaust with dual mufflers, reprogrammed Turbo Hydramatic 200-4R transmission with a custom torque converter and transmission cooler, and unique differential cover/panhard bar included more of the performance modifications. Exterior styling changes include vents located on each front fender, 16 inch black mesh style wheels with VR-speed rated tires, and deletion of the hood and fender emblems. The interior changes of the GNX included a serial number on the dash plaque and a revised instrument cluster providing analog Stewart-Warner gauges, including an analog turbo boost gauge. Performance was measured faster than the Ferrari F40 and the Porsche 930 with a quarter mile time of 12.7 seconds at 113.1 mph (182 km/h) (0.3 and 0.8 seconds quicker, 2.9 and 13.3 mph faster) and a 0-60 mph (97 km/h) time of 4.6 seconds (0.4 and 0.3 seconds quicker, respectively). GNX #001 is the 1986 prototype currently owned by Buick and sometimes makes appearances at car shows around the US. The GNX used a unique torque arm that was mounted to a special, GNX only, rear differential cover, for increased traction. The torque arm rear suspension alters the suspension geometry, making the body lift while planting the rear tires down, resulting in increased traction.
The stealthy appearance of the all-black GNX and Grand National (and the resemblance of its grill to his helmet's mouthpiece), coupled with the fact that the Grand National was initially released during the popularity of Star Wars movies, earned it the title "Darth Vader's Car". Car and Driver covered the GNX model's introduction with the headline "Lord Vader, your car is ready." Due to the six cylinder engine, the Buick make, and the black paint Grand Nationals were sometimes referred to as the "Dark Side". The "Dark Side" contrasted with the more common V8 Mustangs and Camaros that were popular at the time.
